Harrison Roofing Services are dedicated to excellence, safety and efficiency in everything that we and our sub-contractors do.

In order to maintain our high standards, we actively seek accreditation by leading industry organisations, who share our values and our commitment to Safety, Fair Pay, and Efficiency.

We are proud to be accredited by the following outstanding organisations. 


As a leading Roofing Contractor, we are firmly aligned with the guiding principles of The National Federation of Roofing Contractors, the UK’s largest roofing trade association. With a history spanning 125 years, NFRC has established itself as the voice of the roofing industry, constantly adapting to change and innovation to ensure its members are at the forefront.


CHAS is a trusted advisor on health and safety compliance, which syncs with our Key Value of Safety. CHAS is dedicated to setting industry benchmarks and providing assurance and reassurance. Harrison Roofing Services and CHAS are invested in helping everyone work safer, more efficiently.


Our accreditation by Safemark is a symbol of our ongoing commitment to the safety of our team and everyone around us. Safemark is a pre-qualification assessment scheme that is Safety Schemes in Procurement (SSIP) member-assessed. Contractors (or sub-contractors) with Safemark have been assessed and confirmed by an SSIP forum member as meeting acceptable health and safety standards. Accreditation is renewed annually by reassessment.


An accreditation by the SafeContractor scheme reassures our clients that health and safety are of paramount importance to us. The SafeContractor auditors have reviewed our health and safety policies, procedures and documentation to assess there is suitable and sufficient health and safety compliance within our business, and we have successfully completed a risk assessment questionnaire.  

Living Wage Employer

We believe in a fair day’s pay for a hard day’s work, leading to our accreditation by The Real Living Wage. Voluntarily paid by almost 4,000 UK businesses, the real Living Wage is higher than the government minimum. 


Harrison Roofing Services offer a full range of roofing, including single-ply. Our commitment to excellence means we’re accredited by the trade association for the single-ply roofing industry, The Single Ply Roofing Association (SPRA). SPRA members are actively involved in the monitoring, development and reporting of cutting-edge technologies to improve single-ply products, installations and aftercare. SPRA members also believe that quality comes through knowledge and skills. 

British Safety Council

We are delighted to be recognised by the British Safety Council. Their vision is that nobody is injured or made ill at work, which aligns with our own key Value of Safety. For over 60 years they British Safety Council has strived to keep people safe through the provision of education, guidance and support.


As we endeavour to maximise efficiency and proficiency in everything we do, Harrison Roofing Services are proud of our accreditation by Constructionline, the UK’s leading procurement and supply chain management service. Constructionline collects, assesses and monitors standard company information through a question set that is aligned to PAS91, the standard pre-qualification questionnaire developed by BSI to reduce duplication within the construction industry.


As a member of the SMAS, Harrison Roofing Services further showcases our commitment to Health & Safety. SMAS is a member of Safety Schemes in Procurement (SSIP) and works with many of the major UK housebuilders and other construction organisations.


Safe2Torch is an NFRC campaign, developed in partnership with contractor and manufacturer members of the NFRC, that seeks to significantly reduce the risk of roof fires when using gas torches, either to dry out roofs or when used to install torch-on membranes. Our association with Safe2Torch directly aligns with our mission to maintain the safety of our team and everyone around us.


Harrison Roofing Services are proud to be accredited by Acclaim as it allows us to demonstrate our compliance with health and safety legislation. Acclaim Accreditation is the SSIP member scheme provided by Capita Supplier assessment services. It uses the expertise and knowledge of Capita Property and infrastructure, leaders in health and safety consultancy, to appraise each application.
